What is erosion?
Erosion is the process by which soil and rock are removed from the Earth’s surface by natural processes such as wind or water flow.
Name the three main types of erosion.
Water erosion, wind erosion, and ice erosion.
What type of erosion is primarily responsible for shaping coastlines?
Coastal erosion.
Fill in the blank: Coastal erosion is influenced by _____, wave action, and human activities.
tides
What is hydraulic action in the context of coastal erosion?
Hydraulic action is the force of waves crashing against coastal rocks, causing them to break apart.
Which human activity can exacerbate coastal erosion?
Construction of sea walls and other coastal structures.
What role does vegetation play in preventing erosion?
Vegetation helps to anchor soil in place and reduce the impact of rainfall and wind.
True or False: Urbanization has no effect on erosion rates.
False
What is the primary cause of increased erosion in urban areas?
The removal of vegetation and soil compaction due to construction.
What is the term for the gradual wearing away of rocks by wind-blown particles?
Abrasion.
What are some consequences of coastal erosion?
Loss of land, damage to property, and loss of habitat for wildlife.
What is sediment transport?
Sediment transport is the movement of solid particles, typically due to wind, water, or ice.
Fill in the blank: The area where land meets the ocean is called the _____ zone.
coastal
What human practices can help in managing coastal erosion?
Implementing beach nourishment, restoring wetlands, and using natural barriers.
What is the impact of climate change on coastal erosion?
Climate change can increase the rate of coastal erosion due to rising sea levels and more intense storms.
